Also known as a 22 degree halo or a sun halo, the ring is caused by sunlight passing through ice crystals in cirrus clouds within the Earth's atmosphere, the University of Illinois' Weather World Project 2010 explains. (See WW2010's website for diagrams that illustrate how it works.)
The crystals bend direct sunlight, projecting it elsewhere into the sky, and at a certain angle -- you guessed it, 22 degrees -- a halo can be seen around the sun.

Working outside, I see at least one of those a month. Usually have a good chance to see one during times of heavy 'contrailing', so I call them chembows.
